Df(2L)HisC, His4rΔ double homozygotes rescued by 12x copies of the HisGU gene unit (bearing His1HisGU.wt, His2AHisGU.wt, His2BHisGU.wt, His3HisGU.wt and His4HisGU.wt) are semi-lethal and adults are fertile and show normal lifespan.

Epidermal Df(2L)HisC clones in His4rΔ homozygotes that also express variants of the HisGU gene unit (12 copies; bearing His1HisGU.wt, His2AHisGU.wt, His2BHisGU.wt and His3HisGU.wt with either His4HisGU.wt, His4HisGU.H4K16R, His4HisGU.H4K16Q or His4HisGU.H4K16A) are able to form normal-looking adult structures with sensory bristles.

Complementation and Rescue Data
Comments

Clones containing Df(2L)HisC mutant cells stop proliferating, but are rescued in animals that also carry four copies of M{3xHisGU.wt}.

Increasing copy numbers of the histone gene repeat unit provided by transgenic constructs can rescue the Df(2L)HisC phenotype: Df(2L)HisC homozygotes that are also homozygous for M{1xHisGU.wt} develop a defective cuticle. Df(2L)HisC homozygotes that are also homozygous for M{3xHisGU.wt} develop a wild-type cuticle pattern but fail to hatch. Df(2L)HisC homozygotes that carry four copies of M{3xHisGU.wt} (homozygous for two different insertions of M{3xHisGU.wt}) are rescued to become fertile adults with no visible morphological defects.
